GENERAL INSTRUCTIONS

IMPORTANT

The equipment covered in this manual is to be installed by
trained, experienced service and installation technicians.
Any heat pump is more critical of proper operating charge
and an adequate duct system than a straight air conditioning
unit. All duct work, supply and return ducts, must be
properly sized for the design airflow requirement of the
equipment. ACCA is an excellent guide to proper sizing.
All duct work or portions thereof not in the conditioned
space should be properly insulated in order to both
conserve energy and prevent condensation or moisture
damage.

SHIPPING DAMAGE

Upon receipt of equipment, the carton should be checked
for external signs of shipping damage. If damage is found,
the receiving party must contact the last carrier
immediately, preferably in writing, requesting inspection
by the carrier’s agent.

GENERAL

The refrigerant system is completely assembled and
charged. All internal wiring is complete.

The unit is designed for use with or without duct work.
Flanges are provided for attaching the supply and return
ducts.

These instructions and any instructions packaged with any
separate equipment required to make up the entire heat
pump system should be carefully read before beginning the
installation. Note particularly “Starting Procedure” and any
tags and/or labels attached to the equipment.

While these instructions are intended as a general
recommended guide, they do not supersede any national
and/or local codes in any way. Authorities having
jurisdiction should be consulted before the installation is
made.

FIELD INSTALLED HEATER PACKAGES
(OPTIONAL)

These packaged heat pumps are manufactured without
supplementary electric heaters. Supplementary heaters are
available for simple, fast field installation.

A separate power circuit is required for the supplementary
heaters.

IMPORTANT: Refer to Table 1 when designing duct work
for maximum available static pressure with heater installed.

Refer to Tables 2 and 4 for proper application information
on all available heater combinations and what units they
can be used with. It also shows the applicable circuit
ampacities, fuse size, and wire size for each heater
combination.

These instructions explain the recommended method to
install the air cooled self-contained unit and the electrical
wiring connections to the unit.

INSTALLATION

LOCATION

GENERAL

The unit must be located outside, or in a well ventilated
area. It must not be in the space being heated or cooled. A
sound absorbing material should be considered if the unit is
to be installed in such a position or location that might
cause transmission of sound or vibration to the living area
or adjacent buildings.

SLAB MOUNTING

In areas where winter temperatures DO NOT go below
32°F for periods over twelve hours, the unit may be slab
mounted at grade level. When installing unit at grade level,
install on a concrete slab at least four inches above finished
grade level. Slab should have a slope tolerance away from
the building structure of at lease ¼ inch per foot, while
being level from side to side. This will prevent ice buildup
under the unit during defrost cycles. Place slab in a
location where runoff water from higher ground will not
collect around unit. See Figure 2.

A minimum of 24 inches should be provided between the
coil inlet and any building surfaces. Provide a minimum of
three feet clearance on the service access side of the unit.
See Figure 3.

When a unit is installed in areas where low ambient
temperatures or strong winter winds exist, it should be
placed so prevailing winter winds are not in direct line with
the heat pump coil. If this is not possible, a wind barrier
should be constructed. Place barrier 24 inches from the
coil inlet side of the unit and in the direction of prevailing
winds. Size barrier at least the same height and width as
the unit. This may be necessary on ground level
installations, also. See Figure 3.

WINTER INSTALLATION BELOW 32°F

In areas where winter conditions go below 32°F for
extended periods, the unit must be elevated above the
mounting surface to prevent snowfall or defrost ice
accumulation from interfering with the operation of the
unit. A minimum of twelve inch elevation is
recommended, while greater elevation may be required for
areas of high snow accumulation. Poured concrete, steel
framework, brick, cement block, etc., can be utilized to
construct a suitable raised mounting platform. See
Figure 4.

TYPICAL INSTALLATIONS

1.

ROOF MOUNTED

sturdy base on the roof of the building. Return air to
the unit is brought through a single return grille (grilles
with built-in filters are best since they enable easy
access for filter changing). Return air ducts are
attached to the lower section of the front panel. Supply
air is brought from the unit to attic duct work or to a
furred down hall. Supply air duct is attached to the top
of the front panel.

CAUTION: All outdoor duct work must be thoroughly

insulated and weatherproofed. All attic duct
work must be thoroughly insulated. Two inch
thick insulation with suitable vapor barrier is
recommended for both outdoor and attic runs.

In roof top installation, as in all installations, the heat
pump must be level from side to side. However, the
unit should have a pitch along the length to assure
complete external drainage of precipitation and of
defrost condensate.

2.

CRAWL SPACE

space must be well insulated and provided with a vapor
barrier. In addition, the crawl space must be
thoroughly ventilated and provided with a good vapor
barrier as a ground cover. It is most desirable to install
the unit outdoors rather than inside the crawl space, so
that it will be readily accessible for service. In
addition, it is necessary to dispose of the condensate
from the outdoor coil on the heating cycle, and this is
virtually impossible with the unit installed inside the
crawl space.

3.

SLAB MOUNTED AT GROUND LEVEL

type installation is ideal for homes with a slab floor
construction where a roof mounted unit is not desired.
The supply and return duct work can be run through a
furred closet space.

4.

THROUGH THE WALL

requires a suitable framework to be fabricated capable
of withstanding the unit weight. Normally the unit will
be insulated so as to minimize supply and return duct
work.
